  • Commented on Invisible Sun: Themes and Nightmares
    In the extremely unlikely future where the entire NSG cuts them off, sure. Or you could secure yourself against such paranoia by just buying 2 more fuel loads with every sub from the word go. Nuclear fuel is not diesel,...
  • Commented on Invisible Sun: Themes and Nightmares
    The French design of naval reactors is that they use civilian enrichment grade fuel. Which means, you can refuel them unless you manage to get blacklisted by the entire Nuclear Suppliers Group. Heck, given Australia is a major uranium miner.....
  • Commented on Fossil fuels are dead (and here's why)
    Nuclear subs make a lot of sense for Aus. Lot of coast line, lot of tradelanes that need to be open. Conventional subs dont have the legs, and anything on the surface is way too vulnerable to mass missile strikes...
  • Commented on Fossil fuels are dead (and here's why)
    I am honestly just confused. Sure, the shortfin is a monstrosity nobody should ever buy.. but if the Australians have gotten over their fear of nuclear cooties, why the heck not just change the order already in progress to proper...
  • Commented on Invisible Sun: Themes and Nightmares
    If Star Treks writers had thought it through, then the transporter would have required a receiving and transmitting beacon. So step one is the enterprise launching a missile carrying one. This makes a lot of plots easier, because they can...
  • Commented on Fossil fuels are dead (and here's why)
    So, stepping slightly off the usual strange attractors of this forum, if beamed power is not practical, then what is the "has an economic return" use case for large volume launch capacity? A: Mining. And other very dirty industry. You...
  • Commented on Fossil fuels are dead (and here's why)
    Two projects. China has two molten salt projects. One is solid fuel, salt cooling, the other is full-bore molten salt. They also has a sodium cooled reactor project, which is basically a license build BN-series. Basically, their gen-4 reactor project...

I *think* this is saying they are loading the reactor with non-nuclear salts...
  • Commented on Fossil fuels are dead (and here's why)
    The Chinese salt reactor was supposed to go online in 2020, but Covid. - the plans have been public for years, and China has been publishing a fair bit of interesting stuff in the fields of molten salt corrosion control...
  • Commented on Fossil fuels are dead (and here's why)
    Re: Nautical reactors. The US designs are entirely useless for any civilian purpose, because what the US does is take a large amount of weapons grade fissile, then alloy it with burnable neutron poisons, then use that as reactor fuel....
  • Commented on Fossil fuels are dead (and here's why)
    What Denmark actually has that the UK does not is "Norway and Sweden". There is no Danish grid as such, there is only Nordpool. 1.7 gigawatts of interconnect into Norway, over two to Sweden. This would not be that much...
  • Commented on Fossil fuels are dead (and here's why)
    Denmark has one of the very best wind resources on the planet. We are still net importers to the tune of twenty percent of our total electricity consumption, and transient importers to much, much higher percentages than that. I have...
  • Commented on Fossil fuels are dead (and here's why)
    The fastest grid transformations on record were the Messmer plan, and the decision of Sweden get off oil for their non-hydro power. Nations have tried really hard to accomplish similar things without resorting to reactors, and well, not only has...
  • Commented on Because I am bored ...
    Looked up the tables for 1900. Horror show for under five with just shy of 20% mortality, but school age children had a 99 percent chance of making it to adulthood. So.. Yhea, that is mass murder....
  • Commented on Because I am bored ...
    Mentioned this before, but I think the US military is working on post-stealth doctrine. Sensors are getting better, and past a certain point, stealth is just not going to work - if "radars" sense air-flows for example, literally anything that...
  • Commented on Because I am bored ...
    Yes. It is straightforwardly a bank issuing notes "backed" by bitcoin, with much technobabble to disguise that fact, because the overwhelming majority of "investors" in bitcoin have.. let us say Issues with banks....
  • Commented on Because I am bored ...
    The reason people dont use Bitcoins for regular commerce is that it is literally not possible to do so. Remember that long explanation of the technical innards? Transactions are part of new blocks. New blocks are limited per week. Each...
  • Commented on Because I am bored ...
    I am pretty sure Bitcoin was designed to be a scam, because of the inherent transaction limits - You cannot update a blockchain more than single-digit number of times per second. Globally. Across all entries in the ledger. This obviously...
  • Commented on A death in the Firm
    Re: Why things are so expensive to build. This is a general problem, not limited to nuclear power stations, and near as I can tell, it is simply down to most of the western world having really bad doctrine on...
  • Commented on Central Banking on Mars!
    If the people launching it can calculate the trajectory well enough to hit earth so can everybody else. The issue is that the effort involved in tracking things is just completely miniscule compared to the effort involved in moving things,...
  • Commented on Central Banking on Mars!
    Rockets are hot. Mass drivers are hot - or more specifically, their power sources are. We are putting infrared telescopes well away from earth in the solar system *now* - an industrialized solar system will have them all over the...
  • Commented on Central Banking on Mars!
    Everything that gets launched is going to get watched, that is just traffic control. If one of those rockets sets off to fetch a rock and there is not a use and flightplan for that rock filed in triplicate, you...
  • Commented on Central Banking on Mars!
    .. So he thinks the Expanse is a documentary? ... That he thinks that is.. uhm. Terrifyingly plausible. "The high ground is an insurmountable strategic advantage" is a trope that has burned itself into the popular consciousness to an absurd...
  • Commented on Central Banking on Mars!
    ... hilarious future world building: large parts of the solar system is settled, and more or less universally dependent on nuclear fission - the non-mobile bits using a standard staid molten-salts-breeder design, and the rockets using fission fragment designs with...
  • Commented on Central Banking on Mars!
    Oh yes. Random crust is technically a viable ore in terms of energy. Better than coal, even. U is not rare. It is just.. Never going to be economically competitive with asking earth to send you a few tonnes of...
  • Commented on Central Banking on Mars!
    Uranium ores are formed by water flows that contain dissolved oxygen when the flow hits something the uranium wont move through. So anoxic environments likely just do not have good uranium ores at all. On the other hand, high burnup...
  • Commented on Central Banking on Mars!
    That second use is also an abomination. The world should not conform to the will of the long dead, and if you permit inheritance of fortunes at all, the heirs should most certainly have free disposal of the money....
  • Commented on What happens now?
    Basic logic also says that ex-whatevers remain impeachable, due to the doctrine of "Very stupid legal tricks have no place outside fiction", and if resigning your post or running out the clock mooted impeachment proceedings, that would be a very...
  • Commented on Covid on Mars
    The limit on population growth on a colony is child care and education, not wombs. Nobody is going to want semi feral unsupervised kids running around, that is a good way for population growth to go abruptly negative. And if...
  • Commented on Submarine coming through!
    People who depend on cheap cars today are depending on the second hand market. That is what makes most electric options look so very unaffordable - The tech is too new for there to be much of a second hand...
